Abstract

A speaker apparatus selects a path which emits a speaker sound. The speaker apparatus includes a speaker unit for outputting the sound generated from voice data, a body including at least one or more emission paths for guiding and emitting the sound output from the speaker unit, and a member for opening or shutting out at least one emission path.

Claims

1. A speaker apparatus comprising:

a speaker unit for outputting a sound;

a body including at least one emission path for guiding and emitting the sound output from the speaker unit; and

a member for opening or shutting the at least one emission path.

2. The speaker apparatus of claim 1, wherein the member comprises:

a bar which is slidably movable; and

a guide part, installed in the body, for guiding movement of the bar and wherein the at least one emission path is opened or shut according to a movement position of the bar.

3. The speaker apparatus of claim 2, wherein the bar comprises a through hole for being opened to outside the body, and wherein the through hole is opened to or is not opened to the at least one emission path according to the movement position of the bar.

4. The speaker apparatus of claim 2, wherein the guide part is slantingly installed relative to a predetermined surface of the body.

5. The speaker apparatus of claim 2, wherein the guide part comprises at least one projection therein for frictionally engaging the bar for obstructing movement of the bar.

6. The speaker apparatus of claim 2, wherein the bar has a streamlined configuration.

7. The speaker apparatus of claim 1, wherein the body is a case frame having an appearance of a portable terminal.

8. The speaker apparatus of claim 2, wherein the bar, responsive to a load of the bar, moves along a slope of the guide part.

9. The speaker apparatus of claim 2, further comprising at least one electromagnet capable of generating an electromagnetic field when an electrical current is supplied, for moving the bar to a corresponding position in the guide part, wherein the bar includes a metallic member for being attracted by the electromagnetic field.

10. The speaker apparatus of claim 9, wherein the speaker unit, installed in a portable terminal for performing a plurality of functions, supplies the electrical current to the at least one electromagnet when a selected function is performed.

13. An electronic device comprising at least one speaker apparatus according to claim 1.

11. A speaker apparatus comprising:

a rotatable speaker unit for emitting a sound;

a weight member, attached to the speaker unit, for generating a moment and for rotating the speaker unit; and

a body including at least one outlet, wherein the sound is emitted through the at least one outlet of the body according to a rotation direction of the speaker unit.

12. The speaker apparatus of claim 11, wherein the body is a case frame having an appearance of a portable terminal.

14. An electronic device comprising at least one speaker apparatus according to claim 11.

15. A speaker apparatus comprising:

an external surface with an externally exposed outlet therethrough;

a speaker unit for outputting a sound;

an internal emission path for conveying the sound from the speaker unit to the outlet;

a guide adjacent to the outlet; and

a bar, movable within the guide, for selectively blocking the emission path, thereby controlling the outputting of the sound.

16. The speaker apparatus of claim 15, wherein the bar includes:

a bar surface; and

a through hole extending through the bar surface;

wherein, when the bar is in a first position in the guide, the bar surface is adjacent to the emission path and the outlet, thereby blocking the outputting of the sound from the speaker to the outlet; and

wherein, when the bar is in a second position in the guide, the though hole is adjacent to the emission path and the outlet, thereby allowing the outputting of the sound from the speaker to the outlet.

17. The speaker apparatus of claim 15, wherein the guide is oriented at a slant relative to the external surface, whereby orientation of the speaker apparatus and gravity cause the movement of the bar in the guide to control the outputting of the sound.

18. The speaker apparatus of claim 15, wherein the guide includes a projection therein for frictionally engaging the bar for obstructing movement of the bar.

19. The speaker apparatus of claim 15, further comprising:

at least one electromagnet, capable of generating an electromagnetic field when an electrical current is supplied, for moving the bar in the guide to control the outputting of the sound,

wherein the bar includes at least one metallic member for being attracted by the electromagnetic field when the electrical current is supplied to the electromagnet.

20. The speaker apparatus of claim 19, wherein the at least one metallic member includes:

a pair of metallic members disposed on opposite ends of the bar; and

wherein the at least one electromagnet includes;

a pair of electromagnets disposed at opposite ends of the guide, with each electromagnet for attracting a respective metallic member on the bar, thereby moving the bar within the guide to control the outputting of the sound.
